Hi, I was told I need to have the o2 sensor replaces (bank 1 sensor 1) but I'm looking on line and there are so many different kinds (wire # and heated/unheated) which one do I need. Thank you, Sue

If u had a code p0133 then u would replace th o2 sensor in the exhaust manifold u can see it when u open the hood it's right there. Let me know how it goes.
